Alan Gross , the American contractor at the center of one of the biggest U.S. foreign policy reversals in a half century, was released from a Cuban prison as President Obama announced today that the U.S. was normalizing relations with Cuba.

During an address translated in English, Cuban President Raul Castro talked about his phone conversation with President Obama. Castro said the exchange of prisoners with the U.S. "doesn't mean the main issues have been resolved."
